Multiple addons using the same name
In windows OS you can open the console form the menu:

Window->Toggle System Console:



There you should be able to find information on your error.

In your case you have a duplicated addon. This error can happen when you have two versions of the same addon as well.

The duplicate could be in two places:

On the programs folder in your system drive:


C:\Program Files\Blender Foundation\Blender\ version number \scripts\addons


or on the App data folder:


C:\Users\ your user \AppData\Roaming\Blender Foundation\Blender\ version number \scripts\addons


Open both folders, find the duplicate and remove it from the folder.

Then restart blender.
